Maintenance

To ensure the longevity and optimal performance of your SJOYBRING car stereo, follow these simple maintenance guidelines:

• Cleaning the Screen: Use a soft, lint-free cloth to gently wipe the touchscreen. For stubborn smudges, slightly dampen the cloth with water or a screen-safe cleaner. Avoid abrasive materials or harsh chemicals.
• Cleaning the Unit: Periodically wipe the exterior of the unit with a dry, soft cloth. Ensure that no dust or debris accumulates in the buttons or ports.
• Ventilation: Ensure that the ventilation openings on the unit are not blocked. Proper airflow is crucial for heat dissipation and preventing overheating.
• Avoid Extreme Temperatures: Do not expose the unit to extreme temperatures (very hot or very cold) for extended periods, as this can affect its electronic components.
• Power Off When Not in Use: If the vehicle will be stored for a long period, it is advisable to disconnect the car battery to prevent drain and protect the unit.

Troubleshooting

Common Issues and Solutions

• Head unit powers on for several seconds, then shuts down automatically: Some cars' ACC wires are controlled by CANbus or have a "delayed shut off" feature. These cars may not output stable 12V accessory power. You may need to purchase the correct harness adapter (e.g., PAC brand) that provides accessory power for your car model. Alternatively, locate ACC power elsewhere in your vehicle and connect the red wire there.
• No memory function after power off: If the ACC line (Red wire) and the B+ line (Yellow wire) are reversed during installation, the product will not retain memory settings after the power is off. Ensure these wires are connected correctly according to the wiring diagram.
• Screen flashes consistently: This issue might be related to power supply instability or a faulty connection. Verify all power connections are secure and providing consistent voltage. If the problem persists, contact customer support.
• No sound or distorted sound: Check speaker connections and ensure they are correctly wired to the unit's outputs. Verify the EQ settings are not set to extreme levels that could cause distortion. Ensure the volume is not muted.
• Bluetooth connection issues: Ensure Bluetooth is enabled on both the car stereo and your smartphone. Delete previous pairings and attempt to re-pair the devices. Check for any interference from other wireless devices.
